This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated. # Releases ## vercel@50.10.0 ### Minor Changes - feat(cli): Add webhooks command for managing webhooks ([#14789](#14789)) Adds a new `webhooks` command to the Vercel CLI with the following subcommands: - `webhooks ls` - List all webhooks with optional `--format json` output - `webhooks get <id>` - Get details of a specific webhook with optional `--format json` output - `webhooks create <url> --event <event>` - Create a new webhook with specified events - `webhooks rm <id>` - Remove a webhook with `--yes` flag to skip confirmation Webhook event types are fetched dynamically from the OpenAPI spec to stay in sync with the API. - Added experimental services support in the CLI new project flow. When `VERCEL_USE_EXPERIMENTAL_SERVICES=1` is set and a project's `vercel.json` contains `experimentalServices`, the CLI will detect and display the configured services during project setup, automatically selecting the "services" framework preset. ([#14776](#14776)) ### Patch Changes - Improve logsv2 command output format with compact single-line display, text-based level labels, dynamic column widths, and smart date display ([#14767](#14767)) - Skip update check when running on Vercel to prevent unnecessary worker spawning in build container ([#14794](#14794)) - fix --help exit codes for marketplace commands ([#14834](#14834)) - Updated dependencies \[[`687f73cebb6ae1cdd7c7feb0910967de99a17ad6`](687f73c), [`e7c5d5fd41e124ef7314978b351696d130e89917`](e7c5d5f), [`c3104a1ae9dbf9048e08bb2fa85605a95b254876`](c3104a1), [`b029736b4be8dac135bef77283f47e1450faf0a9`](b029736), [`d36c1ad3ddaf9303041e61a0a41d973b02007988`](d36c1ad), [`5b31b133970539986ff9e98013d2c364536bd0b5`](5b31b13)]: - @vercel/next@4.15.21 - @vercel/python@6.5.0 - @vercel/remix-builder@5.5.10 - @vercel/backends@0.0.25 - @vercel/static-build@2.8.28 - @vercel/node@5.5.28 - @vercel/express@0.1.36 ## @vercel/python@6.5.0 ### Minor Changes - vendor Python runtime dependencies ([#14827](#14827)) - Bump vercel-runtime version automatically on its releases ([#14842](#14842)) ## @vercel/python-analysis@0.3.0 ### Minor Changes - initial implementation of Python semantic analysis in Rust ([#14690](#14690)) ## @vercel/backends@0.0.25 ### Patch Changes - Improve handling of cjs/esm interop during imports ([#14798](#14798)) ## @vercel/cervel@0.0.12 ### Patch Changes - Improve handling of cjs/esm interop during imports ([#14798](#14798)) - Updated dependencies \[[`d36c1ad3ddaf9303041e61a0a41d973b02007988`](d36c1ad)]: - @vercel/backends@0.0.25 ## @vercel/express@0.1.36 ### Patch Changes - Updated dependencies \[[`d36c1ad3ddaf9303041e61a0a41d973b02007988`](d36c1ad)]: - @vercel/cervel@0.0.12 - @vercel/node@5.5.28 ## @vercel/fs-detectors@5.7.20 ### Patch Changes - Added experimental services support in the CLI new project flow.

([#14776](#14776)) ## @vercel/functions@3.4.1 ### Patch Changes - Fix InMemoryCache to use JSON serialization for consistency with RuntimeCache ([#14751](#14751)) InMemoryCache now serializes values with `JSON.stringify()` on set and deserializes with `JSON.parse()` on get, matching the behavior of RuntimeCache. This ensures consistent behavior when switching between cache implementations (e.g., in-memory for development, remote for production), particularly for types that don't survive JSON round-trips like `Date`, `Map`, `Set`, and `undefined`. ## @vercel/introspection@0.0.11 ### Patch Changes - Updated dependencies \[[`d36c1ad3ddaf9303041e61a0a41d973b02007988`](d36c1ad)]: - @vercel/backends@0.0.25 ## @vercel/next@4.15.21 ### Patch Changes - Strip routes-manifest.json for determinism ([#14783](#14783)) - Update Next.js adapter version ([#14801](#14801)) ## @vercel/remix-builder@5.5.10 ### Patch Changes - [remix] Prevent 404 responses from being cached with immutable headers ([#14828](#14828)) ## @vercel/python-runtime@0.3.0 ### Minor Changes - vendor Python runtime dependencies ([#14827](#14827)) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>

I'd previously moved these 2 packages out of the backends package so they could be used in isolation, trying to keep the cervel package lightweight for 3rd party usage. At this point in time, I don't think we're ready to make 'cervel' a thing, and it's just making it harder to work.
This PR moves the logic back into the backends package. The other benefit of that is that we can re-use rolldown (previously in
@vercel/cervel) as a loader for the introspection now that they're collocated, so this PR also adds that, allowing us to do introspection on the entrypoint (eg. server.ts) instead of the build output (eg. .vercel/node/server.js)
